BALING PRESS.

Application filed June 28, 1919, Serial No. 307,285. Renewed March 20, 1924.

To all whom it may concern.

Be it known that we, FREDERICK G. MAN- certain new and useful Improvements in 10 Baling Presses, of which the following is a specification.

Th n en ion rela es t imr o ements i baling presses.

One 'of the objects of the invention is to generally improve baling presses.

Another and more specific object is to provide a press especially adaptable for baling oose r p sh me al, 1 1 fo eX ple, as scrap punchings, expanded metal, wire and the like, into condensed or compact bales or bundles for ease of handling; to facilitate transportation and for convenient utilization.

Other, further and more specific objects and uses of the invention will become readily apparent, to persons skilled in the a1 t, from a consideration of the following de scription when taken in conjunction with the drawings wherein Fig. 1 is a side elevation of the press showing the baling chamber closed.

Fig. '2 is an enlarged transverse section taken on line 22 of F 3.

Fig. 3 is a plan view of the press.

Fig. 4 is a central longitudinal section taken on line 4.4L of Fig. 3.

Fig. 5 is an enlarged fragmentary section on the front end of the press, taken on line 55 of Fig. l. I

Fig. 6 is an isometric perspective fragmentary view of the front end of the press.

Fig. 7 is a detail of the cover locking means.

Fig. ,8 is a section taken on line 88 of Fig. '3.

In all the views the same reference characters are employed to indicate similar parts.

The press, as exemplified by the drawings, is designed for relatively heavy work and adapted to be operated by one attendant or operator, its ope-ration being automatic and semi-automatic.

It is fabricated, or built up of standard structural Wrought iron or steel beams in such manner that the maximum stress is borne by the body part of the beams, rather than being transmitted thru the oints which unite the several members of the structure, as in presses heretofore constructed.

The supporting base of the machine is made of two, straight channel beams 10, which are in parallel relation, and secured together at suitable intervals by cross members 11 being bolted thereto. The two front spacing members 11 are extended laterally, as at 12, over the top of the beams 10, into a horizontal plane even with the top of the I-beams 14 and 15. These beams rest upon the tops of the pair of channel beams 10, and are secured thereto, as at 1.6. Snperposed upon the sub-base frame, composed of the members and the transversely disposed I-beams 14- and. 15 is a frame supporting the operative machinery, the front end of which contains the compression chamber 18, this superposed frame being made of a series of channel bars, in pairs, consisting of a lower pair 19, connected by its flanges to an upper pair of similar beams, 20, as at 21, the upper edges of the pair 20, being connected in the same manner to another pair of beams 22, as at 23. These beams entendin unbroken continuity from the front end of the compression chamber to the rear end of the press. The front end of this box-like structure-compressionchamber+rests upon the top surfaces of the channel beams 10, of which the base frame is made, as at 24 *ach of the beams 19, and 22 is outwardly deflected, at intermediate parts, as clearly shown in Fig. v5, to form a diamondshaped compression chamber. Each of the beams 19, 20 and 22 in rear of the chamber are again deflected or caused to inwardly converge so that they rest in a vertical plane ontop of the underlying pair of members 10, of the subbase. The Channel beams 19 extend to the rear of the members 10 and afford a support for the driving mechanism necessary to operate the plunger of the press. The channel members 20 extend rearwardly to a point practically in the same vertical plane with the termination of the members 10, that form the sub-base, and these members are connected together by a transversely positioned member 26, near their terminal ends. The beam members 22 terminate, as at 27, at the rear end of the diamond-shaped structure, that encloses the rounding strap or staple 49.

' movable cover 28 and to retain the loose material being condensed by closing the cover to the compressing chamber.

The frame members 19 and 20, however, which form the compression chamber within which the bale is to be formed, and within which pressure is applied, take the strain of the plunger and the mechanism for operating the same; there being no vertically extending joints, thru which this strain 1s transmitted between the compression chamher and the plunger operating mechanism of the press. The compression chamber is provided with two walls that are adapted to be opened when the press is not in use, the cover wall 28 and the end wall 29. The end wall 29 is intended to be opened, thru which opening the bale may conveniently be removed, the door 29 of which is hinged to the side members 19 and 20, as at 30, and is held in closed position by a latch 31, which is hinged, as at 32, to the opposite side walls 19 and 20, one member of the hinge 33 being secured thereto by the bolts 34. In like manner the hinge member is secured to the opposite members 19 and 20 of the frame by bolts 36. A pintle pin 37, vertically disposed, joins the end door 29 to the hinge member 85, and the latch member 31 is joined to the member 33 by the pintle pin 38. \Vhen the end door 29 is closed, the free edge 39 rests inside of the projection 40 on the latch 31. The latch 31 is moved outwardly, to permit the opening of thedoor 29, by a lever 42, which is bent, as at 43, laterally from a vertical rod 44. Secured to the upper beam 22 is a bracket that affords a bearing for the vertical rod 44 and a similar bracket 46 is secured to the base beam 10 and affords a bearing 4'? for the lower end of the rod. Secured to the rod is a cam 48 which is eccentric therewith and whichpasses thru staple 49 secured to the outside surface of the latch member 31. Now it will be manifest that when the rod 44 is rotated the eccentric will move the latch 31, on its hinge, inwardly into engagement with the adjacent edge of the door 29, and when the eccentric is rotated by the rod 44, in an opposite direction, it will move the latch 31 outwardly by its engagement with the sur- The object of the door is: to permit the easy removal of the bale, or bundle of material that is compressed within the compression chamher after pressure is withdrawn.

The cover 28 consists of a plate 50, which normally rests inside of the door 29 when the compression chamber is closed. The plate 50 is secured to the superposed channel beams 51 and 52 and to an I-beam 53, at

its upper surface. The rear ends of the beams 51, 52 and 53, that are attached to the plate 50 of the cover, are connected to a shaft 54, which has hearings in a box supported on the upper surfaces of the beams 20. The hinge members 56, secured, to the respective beams 51, and 53 provide means for swinging the cover 28 to the open position, shown in dotted lines in Fig. 4.

The shaft 54 is free to be rotated in the boxes 55 but is secured to the members 56 that are fixed to the beams 51, 52 and 53. The shaft 54 extends axially in a lateral direction from the frame, as at 57 and 58, as

shown in Fi". 8 and secured lo the ends of f5 7 the shaft, at each end, is a horizontally ex tending arm 59, each arm carrying a counter-balance weight 60, to substantially counter-balance the door, or cover 28. The weights 60, as a matter of fact, are euiliciently heavy to immediately raise the cover 28 to dotted line position, when it is re leased from its holding means, which latter will now be described.

A pair of arms 61 and 62 are fixed to a transversely extending short shaft 63. The shaft has hearings in two brackets 65, that are spaced apart and project from the loweiu outer surface of the end door 29. The arms 61 and 62 extend upwardly from their lower hinged ends and are deflected rearnnirdly. as at 66, and on their free ends 66. they provide bearings 67 for a transversely cxtending shaft 68 to which an operative handle 69 is connected. The shaft 68 bears an eccentric cam 70 so that when the handle 69 is in vertical position, as shown in Fig. 6, the radially longer part of the cam bears forcibly against the I-beam 53, con. stituting a part of the cover, and forcibly moves the cover into its closed position. In cooperation, this fastening means tends to hold the end door 29 also closed. as well as the cover 28. While the handle 69 is moved, to bring the large part of the cam 70 into contact with the Lheam 53. pressure may be primarily applied to the pivoted handle 71 to force the cover down. The handle T1 is pivoted to a transversely extending shaft 72, as at 73, so that the handle may be thrown back, into the position shown inv dotted lines in Fig. 4, when the cover is in open position or is removed from the com pression chamber. In F ig. 6 the handle (39 is shown in a vertical position. when the cover is forcibly placed in closed position. in order to clearly show the parts, while in Fig. 7 the handle 69 is shown in horizontal position in both positions of operation, the relative position of the cam and handle is a matter of convenience. The shaft 72 finds support in the bearings 75 that are mounted upon the channel beams 51. and 5:2, rcspcr tively, of the cover 28.

The plate 13 forms the bottom of a compression chamber and rests upon the I-beams or sills 14 and 15, and is secured to angle irons 76 that are fastened by rivets, or otherwise, to the side walls afforded by the channel beams 19, on either side of the chamber. The bottom plate 13 terminates at the cross member 77, that is connected to the opposite I-beams encompassing the compression chamber. The front end of the plate is slotted, as at 78, as a provision for inserting a wire, or band, to be fastened around the bale after the substance comprising the bale has been compressed. In cooperation with the slot 78 is a vertical groove 79 in the plunger 80.

The plunger 80 is provided with a head 81, with vertically extending grooves to receive the side wings 82 and 83. The wings 82 and 83 have pivotal movement in the. grooves in which the heads 84 of the wings are received. When the plunger is moved axially of the compression chamber, a spring 85, one on each side, is associated. with the respective wings 82 and 83, yieldingly holds the front ends of the wings in contact with the inner surfaces of the compression chamber. A transversely extending bar 86 is connected to the rear surface of the head 81, of the plunger, and on its extended ends is pivoted a tube 87, one on each end, in which is received an axially movable rod 88. The spring surrounds the tube and has an eX- tended end bearing a hook 89 that passes around the pintle pin 90, in the bracket 91, on the back surface of each of the wings 82 and 83. By this mean the front ends of the wings are yieldingly held in contact with the inner surfaces of the converging walls, afforded by the I-beams 19 and 20, so that as the plunger advances towards the door 29 in the act of compressing the loose substance within the compressing chamber, lateral pressure is applied tothe bale of material by the inward movement of the wings 82 and 83 in the manner described.

lVhen it is desirable to make a smaller bale, as in handling very loose material, the heads 84 of the wings 82 and 83, are placed in the respective grooves .92, made in the head of the plunger, and which contain filler pieces 93 when the outer grooves are employed' for the wings, as shown in Fig. 5. In Fig. 3, however,'the fillers 93 have been removed and the Wings are located within the inner vertical grooves 92 in the head of the plunger. The object of this arrangement is to be able to roduce greater compression and form a smaller bale or bundle of material that is of a more compressible nature.

In association with the inner set of grooves in the plunger we also provide fillers 96, that are placed in the end of the compression chamber, when the end door 28 has been closed. When the ends of the wings 82 and 83 encounter the inner ends of the fillers96, they are deflected more rapidly and to a greater extent, with reference to a given axial movement of the plunger, than when they follow the initial inclination of the inner walls of the compression chamber proper. The fillers 96 are clearly shown in Fig. 3.

Projecting rearwardly from the plunger 80 are a pair of spaced apart brackets, or ears 95. The brackets or ears 95, contain horizontally elongated slots 97 to receive a pin 97 to which is connected a toggle arm 98, as by ins 99, whereby the toggle arm 98 is pivotal y connected to the rear end of the plunger 80. A crushing block 100, having a leg 101 resting on the floor 102 of the plunger, is contained between the pin 97 and the rear wall of the plunger, as a means to safeguard the machinery in the event that an uncompressible mass, at any time, should be contained between the moving plunger and the end door 28 of the compression chamber. In such an event the block 100 will become crushed and the pin 97 will move forward in the slot 97 in which it is contained, there-by satisfying the movement of the mechanism that operates the plunger without producing diastrous effect to the apparatus.

In the event that the block 100 should become crushed, in the manner described, a new block, or a substitute block of the same character may readily be made to replace the broken one with very slight expense.

The head 81 and the floor 102 of the plunger is provided with a groove 103 which. overlies a guide bar 104 that is secured to the bottom plate 13 of the compression chamber. This provision supplies means for maintaining the plunger in the axial center of the compression chamber thruout the en-- tire excursion of its movement.

The arm 98, which is one member of a toggle, and which is pivoted at one end to the rear end of the plunger 80, is also pivoted to another arm 105, consti iting the other member of the toggle, as a pin 106.

The arm is bifurcated at this end and provides two extended spaced apart ends 107 and 108. The other member, 105, of the toggle, is also bifurcated at this end and provides spaced apart ends 109 and 110, which are pivotally supported upon the pin 106 and which are contained between the arms 107 and 108 of the member 98 of the toggle. The member 105 is also bifurcated and provides ends 111 and 112 which are pivoted on a relatively stationary shaft 113 supported on the frame. The pin 113 finds bearing in the pair of I-beams 22, which. at their front ends, constitute part of the compression chamber, as they are extended uninterr-uptedly from the front end of the chamber to a point near the rear end, near the location of the pin 13.

Two spur gear wheels 115, one on either side of the median line of the base frame,

are each supported by the beams 19, on stub shafts 116, leaving space between the two wheels for the passage of a connecting link 117 which is pivotally supported by a pin 118 that is connected to both of the spur gear wheels. The upper end of the arm 117 is connected to the toggle joint and is supported by the pin 106 and thus when the gear wheels 115 are rotated the toggle, comprising the members 98 and is alternately straightened and broken by the link 117 that is connected to the crank arm or pin 106 and the wheels 115. The spur gear wheels are rotated by a pair of pinions that are fixed to a shaft 121 and this shaft finds bearings in the pair of lower beams 19, that also constitute parts of the compression chamber. The shaft 121 extends, at either end, beyond the frame, and carr'es a pair of relatively large spur gear wheels 122 and these spur gear wheels are in driving relation with a pair of spur gear pinions 123 located on the transversely tended compound shaft 124. The one member of the compound shaft 124; also carries a spur gear wheel 125 that meshes with a spur gear pinion 126, secured to the shaft 127 of a motor 128, which furnishes the power for driving the press. By this arrangement of gears the reciprocation of the plunger is effected, at a relatively slow speed with reference'to the sieed of the motor, whilethe effective power of the plunger is correspondingly increased. The motor is supported upon a pair of channel beams 130 that are fixed to the rear ends of simi lar larger beams 19. e

A pair of balance wheels 131 may be se- 7 cured to the compound shaft 12st, as desired,

in order that the momentum thereof may be available in the operation of the press.

For disconnecting the power transmitting mechanism heretofore described, and which is divided for symmetry of action and located on either side of the median plane of the press, I provide the compound shaft 124, which consists of a shaft 124! and a sleeve 133 the latter having enlarged ends 131 and which are preferably hollow, and which form the bearing surface for the sleeve, be ing supported in bearing brackets 135 lo cated on either side of the press frame and secured to the respective channel members 19. The brackets are substantially duplicates of each other and are suitably secured to the respective channel beams. Passing thru the sleeve 133 is a shaft 121,. This shaft is connected, at one end, to one of the balance wheels 131 and to the spur gear wheel 125, as by means of a key 136, and the other balance wheel 131 and the clutch .member 137, are connected to the shaft 124,

as by a key 138. This clutch member is longitudinally movable along the shaft, and is made rotatable therewith by the key 138.

The clutch member 137 is capable of engag ing the clutch member 132 for driving the sleeve 133 from the shaft 121. The pinions 123 are loose on. the shaft 121 and are fixed to the enlarged ends 13 1- of the sleeve 133 as by key 139. Now inasmuch as the motor, or other Source of power, is connected to the wheel 125 on shaft 121, it is independently rotatable because the sleeve 133 is; normally loose upon the shaft 121. The clutch member 132 is connected, as by screws 110 to a disc 1411 which is an integral part of the pinion 123 on the clutch side of the shaft. Now when the two clutch members 137 and 132- are in driving relation, both of the pinions 123 are rotated, because at this time the sleeve 133 and the shaft 121' are made to positively rotate together by the operation of the clutch. 1V hen the clutch members are disconnected, then the motor 128 rotates the shaft 121 and the clutch member 137', and does not rotate the clutch member 132 nor the sleeve 133 to which it is connected.

Since the motor, or other source of power is directly connected to the gear 125, that is fixed to the shaft 124, when th clutch membore 137 and 132 are disconnected, the motor rotates then, only, the shaft 121 with the clutch member 137 and the two balance wheels 131, but the sleeve 133 carrying the pinions 123, by means of which power is communicated to the reciprocating plunger, is not rotated.

The clutch member 137 is controlled by the hand lever 1 1-2, which is provided with a bifurcated end 143 that pivotally engages a ring 1414, within a groove 145 made in the hub of the clutch member 137. The other end of the lever 1 12 is supported upon an extended arm 1-118 and is pivoted to a bracket 1 19, as at 150.

The end door 29 is preferably provided with a lip 28 projecting inwardly from its free end to engage the adjacent side wall of the compression chamber when the door is closed to prevent the side walls from being spread outwardly when pressure is applied to the bale within the chamber. The lip also strengthens that part of the door engaged by the latch member 31, and to remove the stress from the hinge members of the door we place the hinge member 35 back of the front end of the compression chamber and use the hinge of the door in the same manner that the lip 28 is utilized. From confinement between the parts 28 and the hinge of the door 28, the side walls can not spread.

The controlling lever 14-2 which connects and disconnects the clutch members 137 and 132 to start and stop the press, may be made to operate auton'iatically to stop the press when the plunger 80 is retracted in the compression chamber. To accomplish this result, the lever 118 which is pivoted to the bracket 14?, as at 1 1:8" carries an adjustable shoulder 148 which is normally in contact with the outside surface of the lever 142. The inner end of the lever 1&8 is held against a stop M8 by a spring 14:8 A lug 115 projects outwardly from the outside surface of the wheel 115'. When the lug 115 en counters the inner end of the lever 148 and moves it into dotted line position against the spring 148, the shoulder 148 swinging on a circle, the radius of which is the axis of the pivot 148, it moves the adjacent end of the lever 142 inwardly and the remote end thereof outwardly, thereby separating the clutch members and stopping the operation of the press. The spring 1 18, after the lug 115 has passed beyond the lever 14:8, moves it back to its normal position against the stop 148. To again start the machine or press, it is only necessary to move the lever 142 outwardly against the shoulder 148 A rheostat, or starting box 151, may be carried upon the vertically extending rods 152 and is a means by which the motor is started and stopped, and may be the means for regulating the speed of the motor.

From the foregoing description, the use and operation of the machine will become apparent to persons skilled in the art, and while We have herein shown a single embodiment of the invention it will be manifest, to persons skilled in the art, that considerable change in the arrangement and configuration of the parts is permissible within the scope of the appended claims.
